Overview
The CD4043BDR is a CMOS Quad NOR R/S Latch with 3-State Outputs, manufactured by Texas Instruments. This integrated circuit is part of the CD4043B series, which includes quad cross-coupled 3-state CMOS NOR latches. Each latch has separate Q outputs and individual SET and RESET inputs, controlled by a common ENABLE input. This component is widely used in digital logic applications due to its versatile functionality and robust design.
